Pervious Concrete

Grasscrete can complement the design of structures and walkways, throughout residential and commercial spaces. When your are in need a custom low cost design, Grasscrete Molded Pulp Formers are the answer. One distinct advantage that the Grasscrete Molded Pulp Formers have is that they can be easily cut to conform to irregular shapes, winding pathways, along existing curbs, to best conform to the formwork.

Grasscrete provides a variety of landscape solutions while maintaining a sustainable, “Green” product design. As a cast-in-place, monolithic, pervious concrete pavement that is continuously reinforced to provide superior structural integrity, Grasscrete offers the ability to provide year-round access to a variety of applications without compromising surrounding aesthetics or environment. Grasscrete installation costs are significantly lower, production is increased and environmental concerns are virtually eliminated.

The Clovis Community Hospital received a much needed emergency vehicle access road. The access road was recommended by the local fire department due to the need to get fire trucks close to an area that is difficult to reach in case of an emergency. The Grasscrete System was selected for the project due to its strength, durability and aesthetically pleasing design and the ability for driveable grass. Grasscrete Molded Pulp Formers were utilized for this project providing sustainability with their 100% recycled content and ability to degrade over time into the sub-soils. The project was completed within one day due to the Molded Pulp Formers ease of use. The day was spent on preparing the area to receive the Grasscrete pervious concrete system, laying the formers with reinforcement and then pouring the concrete. The former tops were removed and the concrete washed down the second day.

Grasscrete constructed with one time use formers is time proven. Because of its structural integrity and continuous reinforcing, Grasscrete is not subject to the differential settlement that can occur with precast blocks and thin plastic products. The Grasscrete Molded Pulp Former System has been engineered and field proven to bear the continuous weight of up to 114,000 pound vehicles along with such customized applications as military tank use or light speed rail track access– even when the sub-base becomes saturated making this ideal for the Hospital Emergency Access road.

Did you know that Grasscrete can be installed on a slope adequate for slope protection or river embankments? Being structural and continuously reinforced, it allows for vehicle access to the water or over the system without issues such as rutting that would cause bank destabilization with other products.

Grasscrete can be installed on a slope to control erosion while protecting and vegetating banks for both a functional and visually appealing option.

Capable of installing at a slope of 1:2 (50%), Grasscrete has been flow tested to rates in excess of 26 feet per second. This enables it to be used in exacting locations such as emergency spillways. The same testing process has also shown that when used in water flow Grasscrete is hydraulically efficient. Under heavy flow, long stemmed grass is flattened with the resulting thatch reducing the Mannings ‘n’ value for hydraulic roughness to as low as 0.03. Pre-cast concrete systems require infill panels to create directional changes. These spaces can cause turbulent flow that become a focal point for erosion, Grasscrete by contrast is a continuous slab with no such weakness.

Did you know that Grasscrete a green pervious concrete is a great alternative choice for street medians? Did you know that Grasscrete can be used in circular patterns or flowing pathways? Grasscrete for street or road medians is a perfect choice when you want to create an environmentally friendly and functional green space or drivable grass area. Medians provide pedestrian refuge, can reduce the scale of the main street, and with added landscaping, make the public space more beautiful. Grasscrete, a pervious concrete, that uses biodegradable formers, does not restrict site lines and provides ease of access for maintenance workers with minimal maintenance requirements.
